Abstract: An apparatus for dynamic thermal control is provided. The apparatus includes a fan module with multiple fan units, a deflection member configured to direct airflow received from the fan module, and a system component. The apparatus also includes a chassis management controller (CMC). The CMC is coupled to the fan module, deflection member, and the system component. The CMC is configured to dynamically control the deflection member to direct airflow from the fan module to the system component by accounting for at least one environmental element within the apparatus.

Abstract: A system and method for compensating for voltage drops in a device having a remote node is disclosed. A power supply unit has an adjustable voltage output and a feedback circuit. A power path is coupled to the power supply unit to supply voltage to the remote node. A switch has an output coupled to the feedback circuit, a first input coupled to the power path, and a second input coupled to the remote node. A controller is coupled to the switch. The controller is operable to control the switch to switch between the inputs to cause the feedback circuit of the power supply unit to compensate the voltage output for a voltage drop on the power path or the remote node.

Abstract: An apparatus may include a chassis that can receive a sled and a locking mechanism. The locking mechanism can mechanically lock the sled to the chassis to prevent a sudden power loss that can be caused from an unexpected removal of the sled from the chassis. To avoid a sudden power loss, a voltage-sensing electrical switch lock can be implemented to the chassis to mechanically lock the sled to the chassis until the sled is ready to be removed. The sled may include one or more computing devices that need to be inactive before removing the sled. The apparatus includes a controller that may detect whether at least one of computing devices in the sled are in an active state or in an inactive state. Based on the determination of the state of the computing devices in the sled, the controller may activate the locking mechanism or de-active locking mechanism.

Abstract: A system and method for detecting and compensating for temperature effects in a device having a power supply and a remote node. The system includes a power supply unit having an adjustable voltage output and a feedback circuit. The voltage output is adjusted based on the output of the feedback circuit. A power path is coupled to the power supply unit. The power path has power connectors to supply voltage from the power supply unit to a remote node. The remote node is operable to sense a voltage drop of the power path at the remote node associated with temperature effects on the power connectors. An adjustable resistor has an output coupled to the feedback circuit. A controller is coupled to the remote node and the adjustable resistor. The controller determines a resistance value to compensate for the temperature effects and sets the adjustable resistor to change the power output.
